22. Get your electronics set before getting the specimin Is it plugged in? Is it turned on? Check connections Check grounds (plate to cage, cage to rack) Is your amplification correct? Check settings in handout Is your scaling (time base and gain/voltage) correct? You can check the connections and settings on the demo rig or on a classmate’s rig.
